Turkey's highest court is scheduled to consider an appeal by Wikipedia aimingto reverse the Turkish government's more than two-year ban on the onlineencyclopedia.

Turkey blocked Wikipedia in April 2017, accusing it of being part of a``smear campaign'' against Turkey, after the website refused to removecontent that allegedly portrayed Turkey as a country supporting the IslamicState group and terrorist organizations.

Access to Wikipedia and all its language editions was blocked under a lawthat allows the government to ban websites it deems pose a national securitythreat.

Wikipedia declined to remove content from the community-generated site,citing its opposition to censorship.

It petitioned the Turkish Constitutional Court in May 2017 after talks withTurkish officials and a challenge in lower courts failed.

Wikipedia is also appealing the ban at the European Court of Human Rights.
